Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_024675.4(PALB2):c.2650G>T(p.Glu884Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. E884E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Familial cancer of breast Pathogenic:3
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Sep 13, 2023 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 16, 2021 | Loss-of-function variants in PALB2 are known to be pathogenic (PMID: 17200668, 24136930, 25099575). For these reasons, this variant has been classified as Pathogenic. This variant has been reported in an individual affected with breast cancer (PMID: 24415441). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Glu884*) in the PALB2 gene. It is expected to result in an absent or disrupted protein product. - |

not provided Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | May 29, 2018 | This variant is denoted PALB2 c.2650G>T at the cDNA level and p.Glu884Ter (E884X) at the protein level. The substitution creates a nonsense variant, which changes a Glutamic Acid to a premature stop codon (GAG>TAG), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has been reported in at least one BRCA1/2-negative individual with breast cancer (Fernandes 2014) and is considered pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Quest Diagnostics Nichols Institute San Juan Capistrano | Oct 22, 2019 | The variant creates a premature nonsense codon, and is therefore predicted to result in the loss of a functional protein. Found in at least one patient with expected phenotype for this gene, and not found in general population data. - |
